This was one of my favorite TV series of the past 20 years. It was, perhaps unfortunately, too dark and too realistic for its time and did not run sufficiently long to gain a dedicated following. Some of the scenes showing crime victims were disturbing for that day, although they pale in comparison to what is shown on current crime dramas. The cast was great, Walsh and Soul were perfectly cast for their parts. Kent McKord and Richard Kind were also in the cast. Great music by Mike Post and definite Stephen Cannell-style directing touches. Excellent subplots and good character development. As I recall, most of the episodes dealt with serial killers and one of the best was a 2-part episode involving a clergyman. UNSUB certainly prepared the way for series such as CSI and Criminal Minds. There was nothing like it until CSI came out in its first incarnation (Las Vegas) in 2000.
